Melita left and took away the ring left by the cult when she left. As a trading project, as well as thanks to Gao Wen for helping to recycle the ring, Melita made a promise on behalf of the Misin Treasure House:

In the future, as long as there are fragments of eternal stone slabs left behind or similar "non-human things" will be notified of Gao Wen first.

For Gao Wen, the value of this promise is much more valuable than the ring.

But a half-elf who was embarrassed seemed to think so. Amber lay on Gao Wen's desk, pressed her face against the table, slidding like a salted fish, muttering while slimming: "It's such an expensive thing... I took it away like that... I didn't even pay a copper plate... The people in the Mithril Treasure House are too stingy... and they have to have a meal when they leave..."

Gao Wen glanced at the guy with a squinting look: "They will help collect information about Eternal Slate and the like. Don't you think this is more valuable?"

"That can't be spent as money, and that veil woman said it easy. God knows how long it will take for them to find new stone fragments. That's eternal stone! It's not a stone on the road," Amber continued to silence, "Ah, if they can't find it for a hundred years, you can wait for a hundred years?"

Before Gao Wen could speak, he heard this guy continue to whine: "Ah, that's right, you have special skills. At worst, you can get up to death when you get up, and then when they find it, you will ask your descendants to visit you and burn the news to you, and then you can crawl out..."

"From the heart, even if you are really the God of Shadow God, it would be a miracle that you can live so big," Gao Wen jumped and glared at Amber, "Stop talking nonsense and help me open the box over there and take the bag inside the top."

Amber, a salted fish, stepped up from the table, and staggered to the thing while muttering: "Isn't Betty doing it for you normally? Why is it my turn today? Where did the little maid go? I haven't seen her for most of the day..."

"I gave her a half-day vacation and let her take Pea to familiarize herself with this place. Pea is afraid of being angry and can't speak. She is easily frightened when she comes into contact with people in the territory, but she is unexpectedly in tune with Betty, and maybe they can be friends."

While putting the bag of things in front of Gao Wen, Amber came up with a smile: "I tell you, I really appreciate you now. At first I thought your approachable people were all pretending, but now it seems that it is real. People who are not serious can't arrange this step for you."

"That's for your appreciation." Gao Wen was casually perfunctorily, pulling Amber's head aside, and then pouring out everything in the bag.

There were a bunch of dark gray-white crystals inside, with an average size of a little finger. The surface had a little misty color, with a mysterious aura unique to magic materials. However, regardless of the appearance or texture, it did not look like a high-end thing.

"What's this?" Amber had just been quiet next to her for less than two seconds. After seeing these things that seemed to be able to sell for a little money, she immediately came up again: "Crystal? But looking at the poor quality..."

"This is the magic storage crystal that just shipped from Tanzan Town, and it is considered a sample of the first batch of goods. Did you forget? I placed a massive long-term order for Viscount Andrew."

"Demon storage crystal? This thing?" Amber stared at the gray-white crystals for a short time, and suddenly shouted, "That Viscount Andrew won't bring such a trick! We saved his life, so he will use this thing to fool people? This kind of crystal is put in a slightly larger rich mine and is thrown away as slag!"

Gao Wen looked at the swelling half-elves with a little surprise. He never expected that this guy who had no concerns about anything in the territory would be so angry because of the loss of the territory. But he just smiled: "Don't say that it's so exaggerated. This thing is much better than the slag, and that Mr. Viscount didn't cheat anyone at all. He sold these crystals to us at the price of three Cecil silver coins and one taka (weight unit). Where can you find this price?"

"Three silver coins..." Amber quickly thought about how big the newly cast Cecil silver coins were in his mind, and then his face became subtle, "That's really cheap enough... But why do you buy so many inferior magic storage crystals? This kind of quality... I'm afraid only the most basic mage apprentice will use it during practice? And mage apprentice who has a little money may not be willing to use it."

Gao Wen smiled: "Do you know what the biggest problem with this inferior magic storage crystal is?"

"The magic storage ability is only half of the same volume of high-quality crystals, and the energy dissipation is extremely serious, especially the second one, which directly makes them useless," Amber obviously has some understanding of these common sense issues. After all, it involves whether it can be sold for money. "The reason why artificial magic storage crystals are unpopular is also due to this reason."

"Yes, the low magic storage ability is just a small problem. Just put two more crystals. The biggest problem is that the energy dissipates quickly. The magic power charged will disappear by itself in no time. This is a fatal injury to the crystals whose function is to "demon storage", so these crystals become so valuable. Although they have huge reserves, they are difficult to come in handy," Gao Wen said, while opening the locker under the table, taking out a hexagonal metal plate from it and putting it on the table. "But if you change your mind, these crystals that cannot store energy can come in handy..."

Amber looked at the metal plate taken out by Gao Wen curiously. She recognized that this was something Rebecca sent not long ago, as if it was a product from the mechanical manufacturing institute. This metal plate was only a little larger than a palm and was hexagonally shaped. It was a "industrial product" that was pressed out in the machine mold in an instant using the latest "stamping forming technology". On the surface of the metal plate, you can also see neat gully patterns and magic materials embedded in the patterns.

This is a "universal substrate" engraved with magic arrays, and Amber feels that she has seen the rune structure on it.

After trying hard to recall for a long time, she said "Oh": "Oh, I understand, this is the thing that Rebecca and Jenny drew before!"

"The honeycomb magic net unit, which is a basic unit that can be operated alone. I engraved it on a movable universal substrate, and it becomes a 'part' that can be combined with other things at will," Gao Wen said, flipping the substrate over, revealing the empty grooves on the back of the substrate. "And these grooves are connected to other things."

"So this metal plate is constantly gathering magic power now?" Amber looked at this new thing that was completely different from the traditional magic props style. "What are you going to use for these magic powers? Such a small magic net unit should have limited magic power, right?"

"It's indeed limited. It's difficult to even activate a first-level spell based on the output of this magic net unit, so it's necessary to charge the energy into these crystals first," Gao Wen pointed to the inferior magic storage crystal next to it. "After completing a charging cycle, the magic power in the crystal is deducted. Since charging is constantly progressing, the dissipation of the crystal is no longer a problem. You see, it plays a temporary storage device in this system, which is used to store a small amount of magic power generated by the magic net unit. As long as the crystal forms an array and supplemented with a sufficiently long charging cycle, it is entirely possible for such a basic unit to release enough magic power to drive advanced spells."

Amber opened her eyes widened from the moment she heard it, and when she heard it, it was wrong to see Gao Wen at the end: "You guy... do you really confirm that you are a knight?"

"Uh... as for such a big reaction?"

"You are a knight, where did you get these many magic theories?" Amber stared at, then looked incredibly at the magic array substrate and crystal in Gao Wen's hand. They are not combined yet, and there are still many key runes and control magic arrays, but it is obviously not far from being completed. "Is this thing... a magic device? But it seems to be still just a part..."

"Yes, it's still a part, but a very important part. With it, I completed the most important part of my plans: how to solve the problem of mobile energy without the power supply of the stationary magic net," Gao Wen smiled, "I plan to name it Magic Capacitor. What do you think of the name?"

"Magic capacitor?" Amber blinked, "What does this thing have to do with electricity? Are you planning to use it to fire lightning arrows?"

"Uh... OK, I didn't expect this," Gao Wen thought seriously and changed his words, "Then I decided to name it Magic Capacitor."

Amber: “…and bring this one!?”

Seeing Amber's stunned look, Gao Wen felt great joy, so he lowered his head happily and found the drafts he had not finished calculating before. He was preparing to continue to calculate the power and charging efficiency of the honeycomb magic network unit. However, not long after he started working, he suddenly heard a noise from outside.

"I'll go and see what's going on!"

After saying this, Amber disappeared in front of Gao Wen: As long as Gao Wen wrote something, she would definitely feel dizzy and she would be eager to find an excuse to run away at this time.

But she ran out and didn't have much time to come back, and she rushed back again: "Gaowen!Gaowen! Knight Byron is back!"

"He's back?" Gao Wen immediately put down the pen in his hand, "Let him in!"
